A286 washers are known for their outstanding strength, creep resistance, and oxidation resistance at high temperatures once they have been age hardened. As a result, A286 washers can withstand room temperature temperatures of over 1300°F (700°C). The stainless steel alloy A286 (1.4980), sometimes known as Alloy 660 washers, is made up of iron, nickel, and chromium. A286 washers are also corrosion resistant to some extent. While they shouldn't be used in very acidic environments, they offer outstanding oxidation resistance in high-temperature exhaust streams, up to 1500°F (815°C). Their capacity to withstand stress and rupture is far superior to that of other stainless steel grades, particularly stainless steel grade 304. Nickel, molybdenum, titanium, silicon, aluminum, carbon, and acids like phosphoric acid and sulfuric acid are all present in A286 washers. Although they are corrosion resistant in many applications, they should not be utilized in the presence of strong acids like HF or HCL. They are typically found in exhaust systems, manifold applications related to engines, and off-shore oil applications due to their inherent qualities.
